Definitions

  • This invention concerns a method for manufacturing binder for lead storage battery glass mats.
  • lead storage batteries As shown in Figs. 2 and 3, have PbO2 anode plates 3 and Pb cathode plates 4 installed at a specific distance from each other and separators composed of superimposed glass papers 5 and glass mats 6 inserted between the aforementioned electrode plates 3 and 4; the whole is immersed in an electrolyte solution consisting of an H2SO4 solution. 7 is a pole.
  • This kind of glass mat 6 should be durable with respect to the electrolyte solution, in the first place, and it should also have a good permeability for the electrolyte solution and high mechanical strength.
  • the separators with the glass mats 6 and the glass papers 5 superimposed on each other are driven in between the anodes 3 and the cathodes 4, and must have sufficient strength to withstand this driving operation and preserve the aforementioned electrodes; moreover, they should not be invaded by the electrolyte solution, and the electrolyte solution should be able to pass through them easily, from the point of view of producing electrical power. From these points of view, acrylate polymers, which have excellent acid resistance, are used as binders for binding the fiber structure of the aforementioned glass mats 6 and reinforcing them.
  • thermo-crosslikable monomers monomers with hydroxyl or glycidyl groups (Public Patent Bulletin No. 57-26546) or monomers with glycidyl or N-alkylol groups (Public Patent Disclosure Bulletin No. 61-288370), or organosilicon monomers (Public Patent Disclosure Bulletins Nos. 59-203738 and 61-155763) can be used.
  • thermo-crosslinking binders in which these thermo-crosslinking binders are copolymerized, crosslinking reactions occur between the parts introduced from the thermo-crosslinking monomers and the parts introduced from the polymerizable unsaturated carboxylic acid, as time passes. If this phenomenon occurs before processing into the glass mat 6 is performed, there is the problem that the effect of reinforcing the glass mat 6 will be diminished.
  • the aforementioned lead storage battery glass mat binders require that the mechanical strength of the glass mats be reinforced, and also that the quantity of binder adhering to the glass mats be made small, so that the electrolyte solution will flow through them more easily. That is, in order to reduce the quantity adhering to the binder and produce a suitable mechanical strength, it is desirable for the binder to adhere uniformly not only to the surface of the glass mat but also inside it. From this point of view, the viscosity of the binder should be made high, and it has been proposed that the viscosity of the acrylic acid copolymer binder be raised by adding an alkali at the time it is used (Public Patent Bulletin No. 48-277093).
  • an acrylic acid copolymer with a thermo-crosslinking monomer and a polymerizable unsaturated carboxylic acid copolymerized in, is used as the principal ingredient.
  • copolymers with such a structure like the copolymers mentioned previously, crosslinking reactions occur between the thermo-crosslikable monomer parts and the carboxylic acid parts, and the ability to produce the viscosity obtained by thickening with an alkaline substance (abbreviated below as "alkali thickenability") and the property of tight adhesiveness to the glass fibers are greatly reduced over time. Consequently, in the aforementioned binders which use this principal ingredient, the aforementioned properties are also greatly reduced over time.
  • the proposal has also been made to incorporate organosilicon monomers with these binders and thus strengthen the adhesiveness with the glass fibers (Public Patent Disclosure Bulletin No. 59-203738).
  • this binder has an increased adhesiveness to the glass fibers due to the aforementioned organosilicon monomers
  • the principal ingredient of the binder is an acrylic acid copolymer made by copolymerizing a thermo-crosslinking monomer and a polymerizable unsaturated carboxylic acid, and its alkali thickenability and adhesiveness to the glass fibers are still greatly reduced over time due to the occurrence of a crosslinking reaction.
  • This invention was made with these facts in mind. Its purpose is to provide a lead storage battery glass mat binder which exhibits sufficient mechanical strength even though the quantity adhering [to the glass mat] is small, and which does not suffer a decrease in its binder properties over time.
  • the method of manufacturing a lead storage battery glass mat binder of this invention is to mix the following ingredients (A) and (B) and emulsion-polymerize them.
  • Fig. 1 shows a schematic diagram of the structure of the emulsion particles in the binder obtained in an actual example of this invention
  • Fig. 2 shows a cross section of the structure of a lead storage battery
  • Fig. 3 is an enlarged diagram of part A, circled in Fig. 2.
  • 1 Shell part 2
  • thermo-crosslinking monomer part By making a two-layer structure, with the binder particles having a core part and a shell part, by two-stage polymerization, the thermo-crosslinking monomer part could be put into the core part, and the polymerizable unsaturated carboxylic acid part in the shell part surrounding it; in this way, the two parts would not touch each other during storage, and the crosslinking reaction would not occur.
  • the alkaline substance was added at the time the binder was used, dissociation of the carboxyl group in the polymerizable unsaturated carboxylic acid part, present in the shell part, would occur, and the thickening effect would be obtained.
  • the interface between the shell part and the core part would break during the stage of adhesion to the glass mat, and the polymerizable unsaturated carboxylic acid part of the shell part would contact the thermo-crosslinking monomer part of the core part, so that a crosslinking reaction of the two parts would occur, and sufficient mechanical strength would be imparted to the glass mat. In this way, this invention was accomplished.
  • the binder particles of this invention consist of a core part 2, which is made of an alkyl acrylate ester polymer with a thermo-crosslinking monomer part, and a shell part 1, which is made of a copolymer of a polymerizable unsaturated carboxylic acid and an alkyl acrylate ester.
  • the binder containing the binder particles with the aforementioned structure is obtained by a two-stage polymerization.
  • a copolymer of the thermo-crosslinking monomer and the alkyl (meth)acrylate ester is formed; using this as the polymerization seed (the particle which forms the nucleus of an emulsion polymerization), the second-stage emulsion polymerization is performed.
  • a shell is formed, consisting of the polymerizable unsaturated carboxylic acid and the alkyl (meth)acrylate ester, around the aforementioned polymerization seed particles.
  • this invention consists of the following: an ingredient (A), an aqueous dispersion containing the aforementioned polymerization seeds, obtained by the aforementioned first-stage emulsion polymerization, and an ingredient (B), a monomer mixture of the polymerizable unsaturated carboxylic acid used to perform the second-stage emulsion polymerization and an alkyl (meth)acrylate ester; these two ingredients are mixed together and emulsion-polymerized.
  • the aqueous dispersion of ingredient (A) mentioned above uses a raw material mixture consisting of a thermo-crosslinking monomer (a) and an alkyl (meth)acrylate ester (b) as necessary ingredients, and is obtained by emulsion-polymerizing these ingredients.
  • thermo-crosslinking monomer (a) one can use monomers with epoxy groups, such as glycidyl (meth)acrylate or allyl glycidyl, or monomers with hydroxyl groups, such as hydroxyl ethyl (meth)acrylate or hydroxypropyl (meth)acrylate.

On the other hand, if it is greater than 30%, tendencies for the emulsion polymerization to become unstable and for poor film-making of the binder to be produced will be seen.
  • esters of straight- or branched-chain aliphatic alkyl esters or alicyclic alkyl alcohols with carbon numbers of 1-18 and (meth)acrylic acid are ordinarily used.
  • methyl, ethyl, butyl, 2-ethylhexyl, stearyl, or cyclohexyl esters of acrylic acid or methacrylic acid may be used. These esters may be used individually or in combination.

  • emulsifiers used in the aforementioned second-stage emulsion polymerization and the previously-mentioned first-stage emulsion polymerization one can use conventional publicly-known anionic, cationic, or non-ionic emulsifiers.
